TIFFFindCODEC, TIFFRegisterCODEC, TIFFUnRegisterCODEC, TIFFIsCODECConfigured -
codec-related utility routines
const TIFFCodec* TIFFFindCODEC(uint16_t
libtiff supports a variety of compression schemes implemented by software
codecs. Each codec adheres to a modular interface that provides for the
decoding and encoding of image data; as well as some other methods for
initialization, setup, cleanup, and the control of default strip and tile
sizes. Codecs are identified by the associated value of the
TIFF Compression tag; e.g. 5 for LZW
TIFFCodec* TIFFRegisterCODEC(uint16_t scheme, const char
*method, TIFFInitMethod init);
void TIFFUnRegisterCODEC(TIFFCodec *codec);
int TIFFIsCODECConfigured(uint16_t scheme);
The TIFFRegisterCODEC routine can be used to augment or
override the set of codecs available to an application. If the specified
scheme already has a registered codec then it is overridden
and any images with data encoded with this compression scheme will be
decoded using the supplied codec.
TIFFIsCODECConfigured returns 1 if the codec is configured
and working. Otherwise 0 will be returned.
No space to register compression scheme %s. TIFFRegisterCODEC was
unable to allocate memory for the data structures needed to register a codec.
Cannot remove compression scheme %s; not registered.
TIFFUnRegisterCODEC did not locate the specified codec in the table
of registered compression schemes.
